Privacy Policy
Last updated 1 July 2026
This explains what we collect, why, who we share it with, and your choices. Questions: editors@aidatacenterguide.com.
Who we are
The Definitive Guide to AI Data Centers (“the Guide”, “we”, “us”) operates aidatacenterguide.com and is the controller of the personal data described here. Contact us at editors@aidatacenterguide.com.
What we collect
Information you give us
- Email — when you subscribe to the newsletter (confirmed via double opt-in).
- Account details — if you sign in, our authentication provider supplies your email and, if you provide it, your name.
- Content you create — saved calculator scenarios and bookmarks tied to your account, and any correction or feedback you submit.
- Questions to “Ask the Guide” — the text of questions you send to our assistant.
Information collected automatically (analytics — only with your consent)
- Usage events — pages viewed, searches, questions asked, calculator runs — via PostHog (EU region) and our own first-party analytics.
- Approximate location (country, derived from IP) and basic device/browser information.
- We run no advertising trackers, and we do not sell personal data.
Cookies & local storage
Essential (always on, no consent required): your theme choice, your sign-in session, your saved bookmarks and scenarios, and your cookie choice itself.
Analytics (only after you accept): the identifiers PostHog and our first-party analytics use. You choose via the banner; if you decline, no analytics storage is set. You can change your choice by clearing this site’s data in your browser.
Why we use your data (legal bases)
- Consent — analytics, and the newsletter (you confirm via double opt-in). You can withdraw consent at any time.
- Contract & legitimate interests — running your account, saving your scenarios and bookmarks, answering your questions, and keeping the service secure and free of abuse.
Service providers (sub-processors)
We share data only with vetted providers that process it on our behalf:
- Supabase — database and storage for content, accounts, and saved data.
- Render — application hosting.
- Cloudflare — bot protection (Turnstile) on the assistant.
- PostHog (EU) and TigerData — product analytics (only with consent).
- Resend — newsletter and transactional email delivery.
- WorkOS — authentication and sign-in.
- OpenAI and Voyage AI — powering “Ask the Guide”: your question text is processed to generate an answer and, under our API agreements, is not used to train their models.
- Upstash — rate-limiting and caching.
- Stripe — payment processing (when paid plans launch).
International transfers
Some providers are located in the United States. Where required, we rely on Standard Contractual Clauses or equivalent safeguards for transfers out of the EEA/UK.
How long we keep it
Newsletter data until you unsubscribe; account data while your account exists; analytics in aggregate, with raw events kept for a limited period; assistant questions retained to improve coverage. You can ask us to delete your data at any time.
Your rights
EU / UK (GDPR): access, rectification, erasure, restriction, portability, objection, and withdrawal of consent.
California (CCPA/CPRA): the right to know, delete, and correct, and to opt out of the “sale” or “sharing” of personal data — we do neither — plus non-discrimination for exercising your rights.
Exercise any of these by emailing editors@aidatacenterguide.com. If you are in the EU/EEA, you may also lodge a complaint with your local data-protection authority.
Security
Data is encrypted in transit, secrets are held in managed secret stores, and access is least-privilege. No system is perfectly secure, but we work to protect your data.
Children
The Guide is a professional reference, not directed to children, and not intended for anyone under 16.
Changes
We may update this policy and will revise the date above; we’ll note material changes.
The Guide is published by Fehn Originals AS (Norway), which acts as data controller for the processing described above.
